# there is a mis-match between nose and testtools for older pythons.
# testtools will set skipException to be either
# unittest.case.SkipTest, unittest2.case.SkipTest or an internal skip
# exception, depending on what it can find. Python <2.7 doesn't have
# unittest.case.SkipTest; so if unittest2 is not installed it falls
# back to the internal class.
#
# The current nose skip plugin will decide to raise either
# unittest.case.SkipTest or its own internal exception; it does not
# look for unittest2 or the internal unittest exception.  Thus we must
# monkey-patch testtools.TestCase.skipException to be the exception
# the nose skip plugin expects.
#
# However, with the switch to testr nose may not be available, so we
# require you to opt-in to this fix with an environment variable.
#
# This is temporary until upstream nose starts looking for unittest2
# as testtools does; we can then remove this and ensure unittest2 is
# available for older pythons; then nose and testtools will agree
# unittest2.case.SkipTest is the one-true skip test exception.
